Subject: [PATCH] Allow overriding build type via env var

Allow overriding the `CMAKE_BUILD_TYPE` in the `build.sh` script via environment variables.

Mirrors the `LIBRAFT_BUILD_DIR` pattern.

This allows, for example, writing `LIBRAFT_BUILD_TYPE=RelWithDebInfo ./build.sh` to build raft with debug symbols and optimization enabled - without modifying the build script.
